<P>PROBLEM TO BE SOLVED: To conduct appropriate color correction by checking the accuracy of image processing on the occasion of correcting a difference in a color space due to an instrumental error according to each photographing device or nonuniformity in photographing conditions of an illuminating light, environmental temperature or others. <P>SOLUTION: When the photographing device 41a photographs a color chip 421 and acquires a reference photographed image, according to an ID card preparing system 100, it calculates a relative value to a standard photographed image and judges whether this relative value is within the range of prescribed values. When the relative value is within the prescribed values, the device prepares a verification code and also executes correction of 3D-LUT by using the relative value. When the relative value is not within the range of the prescribed values, it makes a display part 414 output a warning. Moreover, the photographing device 41a acquires a face image, executes color correction of the face image by using the corrected 3D-LUT, transmits an ID number, the corrected face image and the verification code to a host 2b of a B branch through a host 2a of an A branch and makes an ID card preparing device 5b of the branch B prepare an IC card. <P>COPYRIGHT: (C)2003,JPO |
